The reaction between - and tetrahydrothiophene (tht) in the presence of NaClO4 gives a solution (probably containing ) that can be used to prepare neutral n> (L = AsPh3, n = 1; L = SbPh3, n = 2; L = 1,10-phenanthroline, n = 1) or anionic - complexes.Treatment of with chlorine or PhICl2 gives trans- or cis-.Isomerizations occur when the cis-isomer is treated with concentrated solutions of chlorine or when the trans-isomer is heated.An X-ray diffraction study of has revealed an almost linear coordination around the gold atom (As-Au-C mean value 177(2) deg).The Au-O distance is too long (mean value 2.80(3) Angstroem) for intramolecular coordination.

The reaction (1:1) between and gives the complex , which on treatment with AgClO4 gives .From this complex, the species , or are obtained by reaction with the corresponding KX salts or neutral ligands.The crystal structure of (obtained by metathesis between the corresponding perchlorate and tetramethylammonium salts) has been determined; the cation displays square plana coordination with two cis-nitrogen (Au-N: 2.166(15), 2.140(14) Angstroem) and two cis-carbon (Au-C: 2.021(16), 2.033(17) Angstroem) atoms bonded to the gold atom.

The isolation of some new three- and four-co-ordinate gold(I) complexes is reported. 197Au Moessbauer data are given for two-, three-, and four co-ordinate complexes, and the technique is shown to be well suited to the determination of co-ordination numbers.For the two- and three-co-ordinate systems the point-charge (partial quadrupole splitting) approach works well, provided that the structures are regular. 31P- n.m.r. data for the Au(1+)-P(C6H11)Ph2 system show that a maximum of three ligands can be bound to the cation.Data for this and other ligands are correlated with the ligand cone angles.Inconsistences between the species present in solution and those obtained by crystallisation are discussed.
